Wikipedia on A.J. Ayer and Mike Tyson

He taught or lectured several times in the United States, including serving as a visiting professor at Bard College in the fall of 1987. At a party that same year held by fashion designer Fernando Sanchez, Ayer, then 77, confronted Mike Tyson harassing the (then little-known) model Naomi Campbell. When Ayer demanded that Tyson stop, the boxer said: "Do you know who the fuck I am? I'm the heavyweight champion of the world," to which Ayer replied: "And I am the former Wykeham Professor of Logic. We are both pre-eminent in our field. I suggest that we talk about this like rational men." Ayer and Tyson then began to talk, while Naomi Campbell slipped out.

“I’m pretty sure that Tyson knew who Ayer was, but, having read Austin, was not much impressed.”

I think I can quote the relevant passage from memory:

“Here we have the common man under the implausible aspect of Ayer himself dribbling brisking in front of his own goal preparing to encompass his destruction.” Or sumthin like that, someplace in Sense and Sensibilia.
